Core characteristics of the E-3 HAWT
From cold climates to remote installations, the E-3 is engineered with simple, rugged components that deliver reliable energy with minimal maintenance in even the harshest conditions.
Blades
Glass fibre, with a high-density polyurethane core and a root reinforcement provides optimum strangth and performance.
Variable pitch
Patented system allows for passive control of the angle of attack of the blades. This innovative system has 2 speeds of action: the first 30 degrees absorb wind gusts and the next 15 degrees act to limit runaway during sustained high winds.
Generator
A new design which optimizes production by keeping all copper conductors within the magnetic field. Together with its 20 poles and N50 neodymium magnets, increases the generation of energy by 15% from the previous model.
Steering rudder
A steel core embedded in high density polyurethane and coated with glass fibre helps to pitch tbhe turbine into the wind, maximizing energy output.
Controller & monitoring
Configurable controller electronics allows the turbine to adapt to the type of grid or batteriesconnected, providing maximum energy generation. Remote monitoring ensures the wind turbine is operating at its peak performance at all times.
